Systems and methods for automatically documenting an accident

ABSTRACT

A system for documenting an accident includes a vehicle that includes a transceiver device and a processing circuit. The processing circuit is configured to receive data from a collision detection device of the vehicle, determine, based on the received data, that an accident is impending or occurring involving the vehicle, generate a request for a nearby vehicle, and transmit, via the transceiver device, the request to the nearby vehicle. The request is for the nearby vehicle to illuminate a region associated with the accident, actively acquire data related to the accident, and record actively acquired data related to the accident.

BACKGROUND

Often, when a car accident occurs, the drivers involved in the accident call the police to document the accident. Each driver will give his or her side of events, and will attempt to provide relevant details, such as the speed and direction that the cars were heading at the time of the accident, etc. Based on these details, the police ultimately determine who is at fault, and an insurance company will also make its own determination of fault based on the police report and driver statements. Frequently, a driver has little factual support, other than his or her statements, in attempting to prove details related to the accident.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

Referring generally to the figures, various embodiments of systems and methods for documenting an accident are shown and described. It is often the case that when a car accident occurs, the drivers involved are primarily responsible for providing the details of the accident. For example, a driver may be required to recall a speed of his vehicle (car, truck, motorcycle, etc.) and a direction the vehicle was travelling at the time of the accident. However, these details are reliant on the driver's recollection of the accident, and the driver may not have been paying close attention to such details when the accident occurred.

According to various embodiments, a processing circuit is utilized to request and/or automatically record data related to a vehicular accident. For example, a car that is involved in an accident can detect that the accident is impending or occurring, and the processing circuit of the car can generate a request for a nearby vehicle (i.e. a “witness” vehicle) to record data related to the accident. By doing so, the nearby vehicle can provide a witness perspective of the accident, and the data recorded can be used in determining liability, damages, etc. The nearby vehicle can be equipped with radar or lidar systems that generate data related to the position, direction of motion, speed, orientation, and/or contour of vehicles involved in the accident. The nearby vehicle can also record specific timing information related to the accident. Any recorded data may be stored by a storage system of the nearby vehicle, the data may be transmitted back to the car that generated the request, or the data may be transmitted to a remote location (e.g., a website, online storage, etc.). As another example, a car may be equipped with a processing circuit configured to detect an accident that is impending or occurring that involves other vehicles (and not the car). Upon detecting the accident of the other vehicle(s), the car can automatically generate data related to the accident (e.g., using radar or lidar systems of the car), and the accident related data may then be stored or transmitted. Additionally, the processing circuit of any of the embodiments herein may be used to determine and store ID information (e.g., license plate numbers, RFID tag information, etc.) related to a vehicle involved in or witnessing an accident, as will be discussed further herein. For example, a car that is involved in an accident may automatically detect and record ID information of a nearby witness vehicle. The car may use a camera, an RFID sensor, radar, lidar, or other collision detection systems/devices of the vehicle to detect the ID information. For example, images from a camera may be analyzed to determine license plate information. As another example, an RFID sensor may be used to determine an RFID tag of a nearby vehicle. It should be understood that although this disclosure often refers to a “nearby vehicle,” interactions with multiple nearby vehicles are within the scope of the present application.

Referring to FIG. 1 a block diagram of system 100 for documenting an accident is shown. According to one embodiment, system 100 includes processing circuit 102 and transceiver device 104. System 100 may also include sensor device 106. Processing circuit 102 is generally configured to interface with an accident detection system of a vehicle. For example, processing circuit 102 may receive real-time data from the accident detection system. In one embodiment, the accident detection system includes camera, radar, and/or lidar devices. Such camera, radar, and lidar devices generally provide data related to the direction/orientation of detected objects, the contour of objects, and the motion of objects (e.g., vehicles on the road, etc.). Based on the information from the camera, radar, and/or lidar devices, the accident detection system or processing circuit 102 can determine that an accident that involves the vehicle is impending or occurring. In response to such a detected accident, processing circuit generates a request to be transmitted to a nearby vehicle, where the request is for the nearby vehicle to record details related to the accident. The request may be transmitted via transceiver device 104. The request may be selectively transmitted only to a specific nearby vehicle or a set of nearby vehicles, or may be transmitted (i.e., broadcast) for reception by all nearby vehicles. Transceiver device 104 includes all components necessary to transmit and receive data. For example, transceiver device 104 may include a radiofrequency transmitter and a radiofrequency antenna, etc. In some embodiments, system 100 includes sensor device 106, which is generally configured to provide data related to an ID of a nearby vehicle. For example, sensor device 106 may include a camera configured to provide video data. From the video data, processing circuit 102 may determine a license plate number of a nearby vehicle. As another example, sensor device 106 may include an RFID sensor configured to provide RFID data. From the RFID data, processing circuit 102 may determine an RFID tag of a nearby vehicle. The RFID tag may include license plate information, or other identification information.

Referring to FIG. 2 a block diagram of system 200 for documenting an accident is shown. According to one embodiment, system 200 includes processing circuit 202, collision detection device 204, and storage device 206. System 200 may also include transceiver device 208. Processing circuit 202 is generally configured to interface with collision detection device 204 to detect an impending or occurring accident involving other vehicles. Collision detection device 204 is configured to provide radar and/or lidar data related to objects (i.e. nearby vehicles) detected using radar or lidar signals, respectively. Collision detection device 204 includes all components necessary (e.g., one or more sensors integrated or coupled to the vehicle) to generate such data and provide the data to processing circuit 202. Processing circuit 202 analyzes the radar and/or lidar data provided to detect an accident. Upon detecting the accident, processing circuit 202 determines relevant details related to the accident (e.g., position of a vehicle, direction of motion of a vehicle, speed of a vehicle, angular motion of a vehicle, orientation of a vehicle, etc.). The details related to the accident may then be stored in storage device 206, which includes components necessary to store data (e.g., physical hard drives, flash storage, etc.). Additionally, processing circuit 202 may store raw radar and/or lidar data from collision detection device 204. In some embodiments, system 200 includes transceiver device 208, which includes all components necessary to transmit and receive data. Any stored data and any data generated by collision detection device 204 and processing circuit 202 may be transmitted via transceiver device 208.

Referring to FIG. 3, a block diagram of processing circuit 300 for completing the systems and methods of the present disclosure is shown according to one embodiment. Processing circuit 300 is generally configured to communicate with a collision detection system (e.g., collision detection device 204) of a vehicle. Processing circuit 300 can analyze data provided by the collision detection system to determine that an accident has occurred or is about to occur involving the vehicle or other additional vehicles. In some embodiments, processing circuit 300 is configured to generate a request to be transmitted to a nearby vehicle. The request is for the nearby vehicle to illuminate the accident scene with radar or lidar probe beams and to hence actively acquire radar or lidar data related to the accident. The request additionally is for the nearby vehicle to record actively acquired radar or lidar data related to the accident. The request for recorded data may encompass both the data acquired in response to the request, as well as previously acquired data concerning the accident (e.g., concerning the location, the requesting vehicle or additional vehicles in the vicinity). Processing circuit 300 may accept input data continuously or periodically. Processing circuit 300 also generates metadata to be included as part of a request. Any of the data generated by processing circuit 300 may also be based on user input or configuration data. In analyzing data from the collision detection system (e.g., camera, RFID, radar, or lidar data), and in generating a request to be transmitted, processing circuit 300 may make use of machine learning, artificial intelligence, interactions with databases and database table lookups, pattern recognition and logging, intelligent control, neural networks, fuzzy logic, etc. Processing circuit 300 further includes input 302 and output 304. Input 302 is configured to receive a data stream (e.g., a digital or analog stream of data) and configuration information. Output 304 is configured to output data for transmission (e.g., a request to be transmitted) or for use in a configuration process of a device having processing circuit 300.

According to one embodiment, processing circuit 300 includes processor 306. Processor 306 may be implemented as a general-purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a digital-signal-processor (DSP), a group of processing components, or other suitable electronic processing components. Processing circuit 300 also includes memory 308. Memory 308 is one or more devices (e.g., RAM, ROM, Flash Memory, hard disk storage, etc.) for storing data and/or computer code for facilitating the various processes described herein. Memory 308 may be or may include non-transient volatile memory or non-volatile memory. Memory 308 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described herein. Memory 308 may be communicably connected to processor 306 and provide computer code or instructions to processor 306 for executing the processes described herein (e.g., the processes shown in FIGS. 5-10). Memory 308 includes memory buffer 310. Memory buffer 310 is configured to receive a data stream from a user input and/or components of a collision detection system through input 302. For example, the data may include input related to radar information or lidar information that was generated by the collision detection system. The data received through input 302 may be stored in memory buffer 310 until memory buffer 310 is accessed for data by the various modules of memory 308. For example, analysis module 316 can access the data that is stored in memory buffer 310. Any data received through input 302 may also be immediately accessed.

Memory 308 further includes configuration data 312. Configuration data 312 includes data related to processing circuit 300. For example, configuration data 312 may include information related to interfacing with other components (e.g., components of a collision detection system, etc.). This may also include the command set needed to interface with a computer system used configure a system having processing circuit 300. This may also include the command set needed to generate a user interface or to communicate with other user interface components of the vehicle (e.g., a touch screen display, etc.). Based on data stored in configuration data 312, processing circuit 300 may format data for output via output 304, which may include formatting data for transmission, etc. For example, processing circuit 300 may generate a request and format the request to be transmitted via a radiofrequency transceiver. Processing circuit 300 may also format data for transmission according to any protocols or standards as specified by configuration data 312. Configuration data 312 may further include information as to how often input should be accepted from a collision detection system. Configuration data 312 may include default values required to initiate communication with any components of the system having processing circuit 300. Configuration data 312 further includes data to configure communication between the various components of processing circuit 300. Memory 308 further includes preference data 314, which is configured to store various user preferences and settings related to the systems described herein. For example, the described systems may be enabled or disabled by a user as specified by preference data 314.

Memory 308 further includes analysis module 316. Analysis module 316 is configured to receive data from a collision detection system of a vehicle (e.g., collision detection device 204) and to determine whether an accident is impending/occurring involving the vehicle or another nearby vehicle. Analysis module 316 may determine the accident based on the data provided, or analysis module 316 may be provided an indicator from collision detection system specifying that the collision detection system has detected the accident. Analysis module 316 also may access configuration information and other data as provided by processing circuit 300. In one embodiment, analysis module 316 instructs request module 318 to generate a request to be transmitted to nearby vehicles.

In one embodiment, analysis module 316 determines if an accident involving the vehicle having processing circuit 300 is impending or is occurring. Analysis module 316 determines the accident by analyzing the data provided from the collision detection system of the vehicle. Analysis module 316 may also access other sensor data (e.g., cameras) and systems of the vehicle to determine operational characteristics of the vehicle (e.g., current speed, current direction, etc.). The collision detection system of the vehicle is generally equipped with radar and/or lidar detection devices. The detection devices generally scan the area around the vehicle and provide information related to objects as discerned from reflected radar and/or lidar signals. Based on these signals, analysis module 316 may decide whether an accident is about to occur, or if the accident is already occurring or has occurred. For example, analysis module 316 may determine that another vehicle is 10 feet in front of the vehicle and is moving 40 mph more slowly than the vehicle is moving. Based on those characteristics, analysis module 316 may conclude that a collision is imminent. As another example, analysis module 316 may detect a sudden change in velocity of the vehicle or another vehicle. As another example, analysis module 316 may determine that another vehicle (or object) is less than a foot from the vehicle, and thus, an accident is occurring, or has occurred. In determining an accident, analysis module 316 may access a priori knowledge relating to the vehicle. For example, analysis module 316 may access configuration data 312 for braking capabilities, steering and handling capabilities, contour and dimension information, weight information, acceleration/deceleration characteristics, etc. Upon detecting an accident, analysis module 316 can direct request module to generate a request to be transmitted to a nearby vehicle so the nearby vehicle acquires and records information related to the accident.

In one embodiment, the collision detection system of the vehicle includes additional sensor devices that provide data to be analyzed by analysis module 316. For example, the collision detection system may include a camera (that captures still images or video), and analysis module 316 may determine that an accident is in progress or has occurred, in part, based on the position or motion of a proximate vehicle that is detected. As another example, the collision detection system may include a microphone device, and analysis module 316 may determine that an accident is in progress or has occurred, in part, based on a loud braking noise or collision noise that is detected. As another example, the collision detection system may interface with the braking systems of the vehicle provide information related to the brakes as they are applied by the driver (e.g., pressures, braking lengths, etc.). As another example, the collision detection system may interface with an airbag system of the vehicle, and analysis module 316 may base an accident determination on whether an airbag has been deployed. As another example, the collision detection system may include an accelerometer, and analysis module 316 may base an accident determination on acceleration/deceleration values.

In one embodiment, analysis module 316 records ID information related to nearby vehicles (e.g., witness vehicles). A vehicle may be equipped with a nearby vehicle detection device capable of detecting nearby vehicles. The nearby vehicle detection device may be separate from or part of a collision detection system (e.g., collision detection device 204) of the vehicle. For example, the vehicle may have a camera system that provides image data to analysis module 316. Analysis module 316 may analyze the image data to determine a license plate number of a vehicle. Analysis module 316 may make use various optical character recognition algorithms in detecting a license plate number. Alternatively, analysis module 316 may use object recognition algorithms to detect a perimeter of the license plate, and store an image including the license plate. As another example, a vehicle may be equipped with an RFID scanning system that provides data to analysis module 316. Based on the RFID data, analysis module 316 may determine ID information for a vehicle. For example, the RFID data may include information for a detected RFID tag of a nearby vehicle. The RFID tag may include the license plate number, or any other identification information for the nearby vehicle (e.g., a VIN number, make and model information, a driver's license number, etc.). Any ID information determined by analysis module 316 may be stored in a storage system of the vehicle (e.g., in memory 308, a hard disk, flash memory, etc.), or it may be transmitted (via a transceiver device). Additional information that is related to the nearby vehicle may also be determined. For example, analysis module 316 may process information from radar and/or lidar systems of the vehicle to determine the position, direction of motion, speed, orientation, and/or contour of a nearby vehicle. The additional information may be stored and/or transmitted along with the ID information. In one embodiment, analysis module 316 analyzes data from a collision detection device of the vehicle to determine whether or not a nearby vehicle was involved in the accident. A determination that the nearby vehicle was not involved in the accident may precede any additional ID information analysis related to the nearby vehicle (e.g., the nearby vehicle may be required to be an uninvolved witness vehicle, etc.). Any of the analysis described herein may also be responsive to a determination that an accident is impending or occurring. In one embodiment, the nearby vehicle is one to which a request as described herein was transmitted (e.g., a request to illuminate a region associated with the accident, to actively acquire data related to the accident, and to record the actively acquired data related to the accident, etc.).

In one embodiment, analysis module 316 receives data from a collision detection device of the vehicle. As discussed above, the collision detection device generally contains one or more radar and/or lidar devices, and may contain additional sensors and components (e.g., cameras, ultrasonic sensors, microphones, etc.). Analysis module 316 analyzes the data from the collision detection device to detect an accident (impending, accruing, or occurred) involving another nearby vehicle (or vehicles). For example, analysis module 316 may analyze radar information to determine that a vehicle in the next lane has rapidly reduced its velocity (e.g., if the driver of the nearby vehicle engaged the brakes, etc.). As another example, analysis module 316 may analyze radar information to determine that two vehicles' projected paths will collide in a certain amount of time. Analysis module 316 may also detect an accident involving other vehicles by interfacing the additional sensors and components of the collision detection device. For example, analysis module 316 may receive audio information and detect a nearby collision sound. As another example, analysis module 316 may receive camera information and analyze images provided by the camera in conjunction with radar information. Any combination of data (e.g., lidar data and camera data, radar data and audio data, etc.) may be used in detecting an accident. Upon detecting an accident, analysis module 316 module may automatically record data related to the accident (e.g., in storage device 206, etc.). Analysis module 316 may record all data (e.g., raw data from all radar or lidar devices), may detect processed data (e.g., position or motion parameters derived from raw data), or may select relevant data (e.g., only data from certain sensors/devices). In one embodiment, analysis module 316 causes processing circuit 300 to accept data at a maximum possible data rate from the various devices discussed herein. Analysis module 316 may also encrypt any data that is stored, and an encryption standard and encryption key may be specified by configuration data 312 or preference data 314.

Analysis module 316 may determine and record specific types of data based on the data received from the collision detection device. In one embodiment, analysis module 316 determines position coordinates of a nearby vehicle. Analysis module 316 may access GPS or mapping information of the vehicle having processing circuit 300 (e.g. from a GPS system or mapping application of the vehicle), and analysis module 316 may store those coordinates along with distance and direction information based on a radar or lidar signal. The coordinates of the nearby vehicle may then be calculated based on the distance and direction the nearby vehicle is from the vehicle. In one embodiment, analysis module 316 determines the velocity and orientation information of the nearby vehicle. In one embodiment, analysis module 316 determines timing information that is stored along with any other determined data. The timing information may be stored with a high precision (e.g., including milliseconds, microseconds, nanoseconds, etc.). Any data that is described herein may be time stamped such that a precise sequence of events may be recreated upon later analysis of stored data. In one embodiment, analysis module 316 determines contour information related to the nearby vehicle. Such information may be compared to a database of vehicle model information (stored by storage systems of the vehicle, or remotely accessed) to determine a likely make and model of the nearby vehicle.

In one embodiment, analysis module 316 may determine that an accident has or is about to occur, at least partially in response to receiving a request to acquire and record data from a requesting vehicle. For example, in an embodiment having a transceiver device (e.g., transceiver device 208), which may be a radiofrequency transmitter, the request may be received by the transceiver device. Upon receipt of the request, analysis module 316 may actively acquire (i.e., by use of illumination and sensing with radar or lidar sensors) and record data from the collision detection device. Analysis module 316 may also analyze the request, which may include identification or positioning information so that analysis module 316 can determine a precise location of which to monitor (e.g., which car to monitor, whether the requesting vehicle or the referenced accident site is on the left side or right side of the car, etc.). Additionally, the request may specify that any recorded data should be transmitted back to the requesting vehicle, or to another location. Analysis module 316 may interface with the transceiver device and provide the signals necessary so that any accident related data generated by analysis module 316 is transmitted in accordance with the request. For example, analysis module 316 may cause the transceiver device to emit a radiofrequency signal to wirelessly transmit the recorded accident related data.

Request module 318 is configured to generate a request for a nearby vehicle, and to control the transmission of the request. The request is for the nearby vehicle to actively acquire (by illuminating a region associated with the accident using radar or lidar probe signals and sensing with radar or lidar sensors) and record information related to an accident involving the requesting vehicle. Request module 318 generates such a request in response to analysis module 316, which detects the accident as it is in progress or is impending, and instructs request module 318 to transmit the request. Request module 318 may include specific instructions and metadata in the request. Request module 318 generates the signals necessary to control a transceiver device (e.g., transceiver device 104) such that the request is transmitted. A request may be transmitted according to any protocol, frequency, or standard which may be predefined and set by configuration data 312 or preference data 314.

In one embodiment, request module 318 generates a request that specifies that all available data should be actively acquired and recorded by a nearby vehicle receiving the request (the “witness” vehicle). Alternatively, the request may specify that only certain types of data should be recorded. For example, the request may specify that radar information or lidar information is desired. The request may specify that only data related to the requesting vehicle is desired. The request may specify that data related to additional vehicles is also desired. The request may specify that data related to a particular site (i.e., that of the actual or predicted accident) is desired. The request may specify a time window for the recorded data (e.g., only that acquired after the request, previously acquired data, both new and previously acquired data, etc.). The request may specify that the witness vehicle additionally acquire and/or record data from passive sensors (e.g., cameras, microphones, etc.). The request may specify that the witness vehicle record identification data regarding the witness vehicle, its operator, or its owner. The request may ask the witness vehicle to acknowledge receipt of the request, to explicitly accept or refuse the request, to report an inability to acquire or record the data, etc. The request may specify that the witness vehicle should store positioning coordinates of the witness vehicle or any other detected vehicles. The request may specify that the witness vehicle store the velocity (translational and/or angular) and orientation of the witness vehicle or of other vehicles as detected by the witness vehicle. The request may specify that the witness vehicle contour information other vehicles as detected by the witness vehicle. The request may specify that the witness vehicle store timing information related to the accident so that any other data stored may be synced.

In one embodiment, request module 318 generates metadata to be included with a request. The metadata may include any number of data items related to the vehicle having the accident. For example, the metadata may include positioning coordinates, velocity and orientation information, insurance information (e.g., policy number, insurance company), contact information for an operator/driver of the vehicle (e.g., a phone number, name, address, etc.), an internet address, payment information, a timestamp of when the request was generated, and/or a vehicle ID (e.g., license plate number, VIN number, driver's license number, etc.). If insurance information is included, such information may be used by the witness vehicle so that the proper insurance company can be contacted and/or provided the recorded data. If contact information is included it may be used so that the driver can be provided the recorded data or so that the driver can be notified that the accident related data has been recorded. The request may also direct the witness vehicle to automatically transmit the recorded data to an external storage location (e.g., a website, a cloud storage service, an FTP site, an email address, etc.) as dictated by the internet address. In one scenario, a witness vehicle may record data or provide access to recorded data for a price. In such a scenario, payment information and an offered price may be included in the request. A price that the driver is willing to pay to have data recorded by a witness vehicle may be previously specified (e.g., by preference data 314). After a request is generated, it is then transmitted by a transceiver.

In one embodiment, a request includes instructs a witness vehicle to transmit any recorded data back to the requesting vehicle.
